LEAD SEAL.

SPECIFICATION forming part of Letters Patent No. 354,036, dated December7, 1886.

Application filed October 11, 1886. Serial No. 215,897. (No model.)

ToaZZ whom it may concern.-

Be it known that I, FRANKLIN W. BROOKS, a citizen of the United States,residing at New York, N. Y., have invented new and useful Improvementsin Lead Seals, of which the following is a specification.

My invention relates to certain new and useful improvements in leadseals; and it has for its object to provide against the stripping of theseal from the wire shackle used in connection therewith.

Prior to my invention many features of construction have been devisedand suggested for accomplishing a purpose similar to that aimed at byme; but none with which I am familiar have proved entirely successful,as most of them are more or less liable to accidental stripping or elsecapable of being tampered with when suitable implements are employed forthat purpose.

My invention consists in forming the seal with a suitable anchor nearthe upper edge, and with threading slots or apertures each 'side of saidanchor, extending through the seal and communicating at the lower edgewith a transverse slot or opening adapted to be closed to prevent accessto the concealed portion of the wire shackle, as will be hereinaftermore fully set forth.

My invention further consists in forming the seal with a preponderanceof metal immediately over the transverse slot, to provide for the properclosing of the latter, as will be hereinalter explained.

5 My invention further consists in casting one end of the shackle in theseal and across the transverse slot, and threading the free end of theshackle and anchoring the same, all as will be hereinafter explained.

40 In order that those skilled in the art to which my invention pertainsmay know how to make and use the same, I will proceed to describe theconstruction and method of using it, referring by letters to theaccompanying drawings, in which- Figure 1 is a plan View of a seal andshackle before the latter has been drawn up and anchored. Fig. 2 is asimilar view with the lead seal shown in section. Fig. 3 is a Viewsimilar to Fig. l, but showing the shackle drawn up against the anchorand concealed and protected by the compression of the lead. Fig. 4

is a similar view with the lead seal shown in section. Fig. 5 is a viewsimilar to Fig. 3, but showing the free end of the shackle threaded inan opposite direction. Fig. 6 is a crosssection of the lead seal,showing the preponderance of metal over the transverse slot. Fig.

7 is a plan view with the lead seal in section, showing a modificationin the form of the cast-in end of the shackle and. the mode of threadingthe free end to interlock; and Fig.

8 is a similar view with the free end of the shackle drawn up intoplace.

Similar letters denote like parts in the several views.

A represents the seahwhich is made of lead, with a solid portion oranchor, B, and wire or shackle orifices or channels at each side of theanchor, as shown at a b. These orifices extend entirely through the sealby communicating with a transverse slot or opening, 0.

C is the wire shackle, one end of which is bent at about a right angleand returned upon itself and cast in the lead seal, as most clearlyillustrated at Fig. 2, although a single bend of the wire may be deemedsufficient, as illustrated at Figs. 4 and 5. The free end of the shackleis passed down through the orifice a and returned through b, as seen atFig. 4, or down I) and up through a, as shown at Fig. 5, until the curveor loop made by the return is drawn up against the solid portion oranchor B. The lead is then compressed by any of the well-knownseal-presses, and the slot 0 is closed by the displacement andcompression of the preponderance of metal shown at D, Fig. 6,effectually concealing the wire shackle contained within the seal andeffectually protecting the same against any manipulation by tools orotherwise. The lower end of the shackle, which is cast within the seal,being returned in U form, as most clearly shown at Figs. 7 and 8, hasone leg below the transverse slot and the other above it; or, in otherwords, 5 the legs of the U are cast in the metal on opposite sides ofthe transverse slot 0, so that when the seal is compressed the legs areforced together and thoroughly bound or tied by the lead.

At Figs. 7 and 8 is shown a modification of the manner of constructingthe cast-in portion IOO or end of the shackle, which, as will be seen,is bent back and forth three times, and so located within the lead withreference to the orifices a b and slot or opening 0 that the free end ofthe shackle may he passedover one side of the first or upper bend and onits return under the other side, and thus when drawn up the bend or loopof the free end of the shackle will straddle the first or upper bend ofthe cast-in portion, and thus serve to strengthen and assist the anchorB; and it will be seen that the lower bent portion,- when the seal iscompressed, forms a dam or bridge across the closed slot 0' and presentsa barrier to the introduction of any tool or implement designed to reachand grasp the loop of the shackle,

which is interlocked with the upper bend of V the cast-in portion andthe anchor.

I am of course aware that it is not new, broadly, to cast one end of theshackle in the lead seal, and I do not, therefore, wish to be understoodas laying claim to any such feature of construction; but

What I do claim as new, and desire to secure by Letters Patent, is-

1. The lead seal A, formed with threadingchannels a b. anchor B, andtransverse slot 0,

all located between the exposed sides or disk.- faces of the seal, incombination with the shackle 0, having one end cast in the seal acrossthe slot a, substantially as and for the purposes set'forth.

2. The seal A, formed with the anchor B near the upper edge, channels a12, passing each side of the anchor and communicating with thetransverse slot 0, in combination with the shackle 0, having its lowestextremity bent and cast in the seal across the slot 0 and returnedacross the seal at or near the anchor B, whereby the threading end oithe shackle may interlock with the upper return portion,and the anchornear the upper edge of the seal,

substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

FRANKLIN W. BROOKS.
